Far more than you think — usually thousands of dollars a year, often tens of thousands. The reason is brutal: most people who can't reach you won't leave a voicemail, and the majority won't call back. They tap the next result and book your competitor. Every missed call is a customer you already attracted, paid to reach, and then lost at the very last step.
Here's how to put a real number on it for your business.
The maths is simpler than it feels
You only need three figures:
- Missed calls per week. Be honest — include after-hours, weekends and the ones that ring out while you're busy.
- Average value of a job. What a typical customer is worth to you on that first job (or more, if you think lifetime value).
- Booking rate. Of the people who couldn't reach you, what share would actually have booked? A conservative 25–35% is common.
Multiply the three together for your weekly loss, then times 52 for the year:
10 missed calls/week × $350 average job × 30% booking rate = $1,050 a week — about $54,600 a year walking out the door.
Change the inputs to your own and the number moves, but the shape rarely does: it's almost always bigger than the cost of fixing it. Our missed-call calculator runs this live so you can drag the sliders to your situation.
Why "they'll just call back" is a myth
It's tempting to assume a serious customer will try again. In reality, when someone's hot water's gone or their power's out, they're in a hurry and there are five other businesses one tap away. Voicemail makes it worse, not better — a beep and silence is a dead end most people won't bother with. The business that gets answered is the business that gets the job, and after hours that's whoever picks up at all.
Where the losses hide
- After hours & weekends. A huge share of urgent, high-value work comes in exactly when no-one's at the phone.
- Your busiest days. The days you're flat out earning are the days you answer the fewest calls — so success quietly costs you future work.
- The second ring. Even during the day, a call that comes while you're on another call usually just vanishes.
The good news: it's cheap to fix
You don't need to hire staff or chain yourself to the phone. Two low-cost fixes cover almost all of it:
- Missed-call text-back — anyone you miss instantly gets a friendly text, keeping them warm until you can ring back. It's a simple automation.
- An AI voice receptionist — answers, qualifies and books every call 24/7, so most calls never become "missed" in the first place. Here's how it works.
Both cost a fraction of the revenue a few recovered jobs represent. When the lost-revenue number is $1,000+ a month and the fix is a couple of hundred, the decision makes itself.
FAQ
Do people call back if you miss them?
Mostly no. The majority won't leave a voicemail, and most won't call back — they ring the next business in the results instead.
How do I calculate my own number?
Missed calls per week × average job value × the share who'd have booked = weekly loss. Times 52 for the year. Our calculator does it instantly.
What's the cheapest fix?
Missed-call text-back and an AI receptionist. Both cost far less than the revenue a few missed jobs represent.
